cf2rdf

The cf2rdf tool performs the following operations:

• Conversion of the CF Standard Names vocabulary to RDF;

• Generation of mapping ontology with the corresponding NVS ontology;

• Registration of the generated ontologies into an ORR instance.

  With the typical configuration these generated ontologies are published as:

  • https://mmisw.org/ont/cf/parameter
  • https://mmisw.org/ont/mmi/cfonmap

Running

Download the latest executable JAR cf2rdf-x.y.z.jar from https://github.com/mmisw/cf2rdf/releases/.

You will only need a Java runtime environment to execute cf2rdf.

cf2rdf expects a number of parameters for its regular execution. These parameters are to be indicated in a local cf2rdf.conf file on the current directory. A template of such file, with a description of the various parameters, can be generated as follows:

$ java -jar cf2rdf-x.y.z.jar generate-conf

Edit cf2rdf.conf as needed.

As command-line arguments for the regular execution, cf2rdf expects:

• either the watchdog argument to check for current remote CF version and trigger conversion and registration in case of new version (based on comparison with latest processed file):

    $ java -jar cf2rdf-x.y.z.jar watchdog
  

• or the desired specific steps to be performed, for example:

    $ java -jar cf2rdf-x.y.z.jar download convert register
  

With a typical configuration:

• The generated ontology files are:
  • cf2rdf_output/cf-standard-name-table.rdf
  • cf2rdf_output/cfonmap.n3
• which get automatically uploaded as:
  • https://mmisw.org/ont/cf/parameter
  • https://mmisw.org/ont/mmi/cfonmap
